Kawirikawiri, transceiver ndi chipangizo chomwe chimatha kutumiza ndi kulandira zizindikiro, pomwe transponder ndi gawo lomwe purosesa yake imakonzedwa kuti iyang'anire zizindikiro zomwe zikubwera ndipo imakhala ndi mayankho okonzedweratu mu maukonde olumikizirana a fiber-optic. Ndipotu, ma transponder nthawi zambiri amadziwika ndi kuchuluka kwa deta yawo komanso mtunda wokwanira womwe chizindikiro chingayende. Ma transceiver ndi ma transponder ndi osiyana ndipo sangasinthidwe. Nkhaniyi ikufotokoza kusiyana pakati pa ma transceiver ndi ma repeater.
Ma Transceiver vs. Ma Transponder: Tanthauzo
Mu kulumikizana kwa fiber optic, ma transceiver a kuwala amapangidwira kutumiza ndi kulandira zizindikiro za kuwala. Ma module a transceiver omwe amagwiritsidwa ntchito kwambiri ndi zida za I/O (zolowetsa/zotulutsa) zomwe zimatha kusinthidwa, zomwe zimalumikizidwa ku zida za netiweki, monga ma switch a netiweki, ma seva, ndi zina zotero. Ma transceiver a kuwala amagwiritsidwa ntchito kwambiri m'malo osungira deta, ma network amakampani, cloud computing, ma network a FTTX. Pali mitundu yambiri ya ma transceiver, kuphatikiza ma transceiver a 1G SFP, 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 200G komanso 400G. Angagwiritsidwe ntchito ndi ma waya osiyanasiyana kapena zingwe zamkuwa kuti atumize deta mtunda wautali m'ma network afupi kapena ataliatali. Kuphatikiza apo, pali ma transceiver a BiDi fiber optic omwe amalola ma module kutumiza ndikulandira deta kudzera mu ulusi umodzi kuti zikhale zosavuta machitidwe a ma waya, kuwonjezera mphamvu ya netiweki, ndikuchepetsa ndalama. Kuphatikiza apo, ma module a CWDM ndi DWDM omwe amachulukitsa ma wavelength osiyanasiyana pa ulusi umodzi ndi oyenera kutumiza mtunda wautali m'ma network a WDM/OTN.
Kusiyana Pakati pa Transceiver ndi Transponder
Ma repeater ndi ma transceiver onse ndi zipangizo zofanana zomwe zimasintha ma signal amagetsi a full-duplex kukhala ma signal a full-duplex. Kusiyana pakati pawo ndikuti optical fiber transceiver imagwiritsa ntchito serial interface, yomwe imatha kutumiza ndikulandira ma signal mu module yomweyo, pomwe obwereza amagwiritsa ntchito parallel interface, yomwe imafuna ma module awiri a optical fiber kuti ikwaniritse kutumiza konse. Ndiko kuti, obwereza ayenera kutumiza chizindikiro kudzera mu module mbali imodzi, ndipo module mbali inayo imayankha chizindikiro chimenecho.
Ngakhale kuti transponder imatha kugwira mosavuta zizindikiro zofananira zotsika, ili ndi kukula kwakukulu komanso mphamvu zambiri kuposa transceiver. Kuphatikiza apo, ma module a optical amatha kungopereka kusintha kwa magetsi kukhala kuwala, pomwe ma transponder amatha kusintha magetsi kukhala kuwala kuchokera kutalika kwa mafunde kupita ku lina. Chifukwa chake, ma transponder amatha kuganiziridwa ngati ma transceiver awiri omwe amayikidwa kumbuyo, omwe nthawi zambiri amagwiritsidwa ntchito potumiza mauthenga akutali m'makina a WDM omwe ma transceiver wamba sangathe kufikira.
Pomaliza, ma transceiver ndi ma transponder ndi osiyana kwambiri pa ntchito ndi kagwiritsidwe ntchito. Ma fiber repeater angagwiritsidwe ntchito kusintha mitundu yosiyanasiyana ya ma signali, kuphatikizapo multimode kukhala single mode, dual fiber kukhala single fiber, ndi wavelength imodzi kukhala wavelength ina. Ma transceiver, omwe amangosintha ma signali amagetsi kukhala ma optical signals, akhala akugwiritsidwa ntchito kwa nthawi yayitali m'ma seva, ma enterprise network switches, ndi ma data center network.
